Fixed Get issues, highlighted by IE10.

1) IE10 seems to interrupt JS execution, in the case of a 304’ing script to invoke
the onLoad handler. If this happened inside the transaction execute loop, the transaction
would terminate early (call onSuccess before all scripts were done), because the _waiting
count would only reflect the number of scripts added to the DOM, when the loop was
interrupted. Changed the logic so that we only finish a transaction when the expected
number of requests are accounted for which seems reasonable in general.

Also wrapped the internal onLoad/onError callbacks in a setTimeout for IE10, so we’re
re-introducing asynchronicty for external onSuccess, etc. app code. We can take this out
when/if the bug below gets fixed.

2) transaction._finish() would move on to the next transaction, before the current
transaction’s onSuccess/Finish/End listeners were invoked, since the logic to move to
the next transaction was invoked before the on listeners were invoked. This meant that
for all browsers, when issuing a CSS transaction followed by a JS transaction, the CSS
success callback wouldn’t be invoked until the JS transaction was initiated.

3) Added user-agent to feature test for async support, because IE10 wasn’t returning true for it.
If IE10 ends up fixing the issue below by GA, we’ll pull out the explicit ua test.

Get should work OK with IE10 now aside from one pending issue. If you issue 2 Get
requests to the same 404ing script, IE10 doesn’t call the success handler for the
subsequent valid (200 etc.) request. This seems to be an IE10 issue, which we cannot
control:

Fixed a bug that could cause CSS requests to hang on WebKit versions between
535.3 and 535.9 (inclusive).

3.5.0

[!] The Y.Get.abort() method is now deprecated and will be removed in a
future version of YUI. Use the transaction-level abort() method instead.

[!] The charset option is now deprecated and will be removed in a future
version of YUI. Specify an attributes object with a charset property
instead.

[!] The win option, which allowed you to specify the window into which
nodes should be inserted, is now deprecated and will be removed in a future
version of YUI. Use the doc option instead, which allows you to specify a
document, as opposed to a window (which makes more sense).

[!] The win property of transaction objects is now deprecated and will be
removed in a future version of YUI. Since any given request in a transaction
may now have its node inserted into any document, the best way to get this
info is to find the request you’re interested in inside the transaction’s
requests property, then look at that request’s doc property to figure out
what document it’s associated with.

[!] The tId property of transaction objects is now deprecated and will be
removed in a future version of YUI. Use the id property instead.

The Get Utility has been completely rewritten to improve performance and add
much-needed functionality. Backwards compatibility has been maintained, but
some methods and APIs have been deprecated and will be removed in a future
version of YUI.

Multiple scripts within a transaction are now loaded in parallel whenever
possible in browsers that are capable of preserving execution order regardless
of load order. This improves performance in those browsers when loading
multiple scripts.

Multiple CSS resources within a transaction are now always loaded
asynchronously, since CSS rules are applied based on the order of link nodes
in the document, not the order in which resources finish loading. This
improves performance in all browsers when loading multiple CSS files.

Script and CSS resources that fail to load due to HTTP or network errors are
now correctly treated as failures in all browsers that support error events
on script or link nodes. Most browsers support this on script nodes, but only
Firefox 9+ currently supports this on link nodes.

CSS load completion is now detected reliably in older versions of
WebKit (<535.24) and Firefox (<9), which don’t support the load event on
link nodes. Unfortunately, while our workaround makes it possible to detect
when loading is complete, we still can’t detect whether it completed
successfully or with an error, so in these browsers CSS resources are always
assumed to have loaded successfully.

Added a Y.Get.load() method, which allows you to load both CSS and JS
resources in a single transaction.

Added a Y.Get.js() method, which is now the preferred way to load JavaScript
resources. Y.Get.script() is now an alias for js().

Added a new Y.Get.options property containing global options that should be
used as the default for all requests, along with similar cssOptions and
jsOptions properties containing default options that apply only to CSS or
JS requests, respectively, and that take precedence over the global defaults.

Added a new pollInterval option, which allows you to customize the polling
interval (in milliseconds) used to check for CSS load completion in WebKit and
Firefox <=8.

The css(), js(), load(), and script() methods now return an instance
of Y.Get.Transaction, which encompasses one or more requests and contains
useful properties and methods for getting information about and manipulating
those requests (and related HTML nodes) as a unit.

The css(), js(), load(), and script() methods now accept an optional
Node.js-style callback function as either the second or third parameter. This
function will be called after the transaction finishes. The first argument
is an array of errors, or null on success. The second argument is the
transaction object.

The css(), js(), load(), and script() methods now accept URL strings,
objects of the form {url: '...', [... options ...]}, or arrays of URL
strings and/or objects. This allows you to specify per-URL options if desired,
such as node attributes, parent documents, insertBefore nodes, etc.

The logic used to determine where a node should be inserted when no custom
insertBefore node has been specified has changed slightly. By default,
script and link nodes will now be inserted before the first <base> element
if there is one, or failing that, before the last child of the <head>
element, or if there’s no <head> element, before the first <script>
element on the page.

The source for the get module has moved from src/yui to src/get. This
allows it to be built separately from the core YUI modules.

No changes.

3.4.0

Added an async option to script(). When set to true, the specified
scripts will be loaded asynchronously (i.e. in parallel), and order of
execution is not guaranteed. The onSuccess callback will be called once,
after all scripts have finished loading.

Added an onProgress callback, which is useful when loading multiple scripts
either in series or in parallel by passing an array of URLs to script().
The onProgress callback is called each time a script finishes loading,
whereas onSuccess is only called once after all scripts have finished
loading.
